LK 863 pump group where mixed supply is desired, a thermic

mixing valve is included. The LK 551 HydroMix has a thermo-

static element that regulates the supply and return to achieve

the desired supply temperature.

LK 864 pump group with a thermic loading valve LK 823 Ther-

moVar®. The pump group is intended to ensure both an optimal

temperature stratification in the storge tank and high return tem-

perature to the boiler, thus increasing the efficiency of the system.

LK 865 is a complete unit for hot water circulation. Consists of

a mixing valve, cross, circulation pump, insulation, connection

kit and three check valves. The LK 551 HydroMix mixing valve

has a thermostatic element that regulates the supply of both

cold and hot water to the desired temperature. The valve has an

anti-scald function that closes for incoming hot water if the cold

water supply ceases.

LK 866 is a pump group with a four way mixing valve, LK 841

ThermoMix®. The pumpgroup is designed for heating systems

where a high return temperature is required to prevent corro-

sion and thus extend the life length of the heat source.

LK 867 is a pump group with a four way mixing valve, LK 830

ThermoMix® B. The pump group has a 4-way bivalent mixing

valve that is designed for heating systems, where energy is

taken from two heating units connected in series or parallel or

for storage tank systems where energy is extracted from two

levels. The pump group should be equipped with an automatic

control unit to ensure that the most favourable heat source is

prioritised at all times.

LK HydronicGroup is a complete pump group that is suitable

for heating where direct supply or mixed supply is desirable.

Consists of a highly efficient circulation pump, insulation, wall

mounting bracket and two ball valves with thermometer, on the

return side there is an integrated check valve.

LK 860 manifold available with or without hydraulic separator

for one, two, three optionally four pump groups. Wall mounting

bracket are included with the manifold.

LK 861 pump group where direct supply is desired.

LK 862 pump group where mixed supply is desired, a three-way

mixing valve is included.
